The event takes place Sept. 20 at the world-famous Playboy Mansion in Beverly Hills, Calif.

The organization announced the Riggs-Misaki fight overnight.

Riggs, who injured his back earlier this year in a loss to Cory Devela, was then slated to fight at Strikeforce’s June event, but he was pulled off the card by the California State Athletic Commission on the eve of the event. However, he returned to action weeks later on July 26 and submitted Matt Dempsey at a Rage in the Cage event in Arizona.

“The back’s great,” Riggs stated in the press release. “It’s 100 percent. I’m really excited to be healthy again and looking forward to getting back on top.”

According to the release, Riggs, who will go for his fifth win in his past six fights, is returning to 170 pounds after the Sept. 20 event.

Misaki, meanwhile, was a longtime Pancrase fighter who debuted with PRIDE in 2004. In 2006 he won the organization’s welterweight grand prix with victories over Phil Baroni, Dan Henderson and Denis Kang.

He’s fought twice in 2008 — with the Japanese-based World Victory Road organization — with two wins, his latest over UFC veteran Logan Clark.

“Joe Riggs is a tremendous competitor,” Misaki stated. “His style is aggressive like mine, so I have no doubt that our fight will be an exciting and memorable one.”
